Radiation Hardness Studies and Evaluation of SRAM-Based FPGAs for High Energy Physics Experiments

SRAM Field Programmable Gate Arrays (FPGAs) are beginning to be considered as viable solutions for particle physics experiments and as well as for space applications. This paper summarise some of the radiation hardness measurements done on the KINTEX-7 FPGA by our group using different particle beams like: protons, X-Rays and ion beams. For multiple values of the total ionizing dose, linear energy transfer and proton energy, the cross sections of single-event-effects are estimated. We also give separate results for specific resources like: configuration RAM, block RAM, I/O banks. Preliminary conclusions are reached for this device regarding its radiation tolerance in LHCb-Upgrade case.
